To all whom it may concern:

Be it known that I, HERBERT H. STEELE,

citizen of the United States, and resident of Marcellus, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- VVriting Machines, of which the following is a specification. My present invention relates especially to inking mechanism for typewriting machines and its general object is to provide improved devices of the character specified.

-More specifically, one object of my invention is to-provide devices which, while they may be employed with the usual ink ribbon, are particularly adapted for use with a ribbon or strip of carbon paperor the like.

One objectof my invention is to provide devices of the character lastreferred to which may be readily and cheaply adapted to existing forms of typewriting machines.

To the above and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

In carrying out my invention in the pres ent instance I have shown it applied to a Monarch t-ypewriting machine but the nature of the invention is such that it may be easily applied to other forms of writing machines.

With the usual form of ribbon an mechanism the ribbon is advanced by the turning of the receiving ribbon spool, which spool ls'revolved through connections wlth the carriage power. The result is that the rate at which the ribbon is fed varies for the reason that when the amount of ribbon the ribbon is reversed, the same continuous increase of r1bbon travel in the opposite direction will occur while the ribbon is winding on the other spool. This mode of feeding, while it. hasproved satisfactory with the usual inking fabric, has disadvantages when employed in connection with a. paper ribbon where a single impact of the type-face drives practically all the carbon or inking material beneath the type face from the paper ribbdn on to the work sheet. It is consequently. highly desirable to provide a longitudinal feed which shall be constant or uniform for the carbon paper and also a feed that at each letter space move ment' shall be of sufficient extent to enable the vertical portions or bars of, successive character impressions to clear each other. These desiderata require that the longitudinal travel of the ribbon shall not be less than 1/64 for each letter space movement of the carriage and shall not vary. My invention.

as herein exemplified accomplishes these results. It is further desirable, in order to avoid waste, that the ribbon feed shall be cut out or rendered inoperative whenever the carriage is released for a continuous advance of greater or less extent-either by operating the release key or by a tabulator key. this end connections are made with the usual tabulating key of the machine and also with the release key, so that when either of said keys is actuated, causing the release of the carriage, theribbon feeding devices are out out or rendered inoperative and no advance of the ribbon will take place during the con t-inuous advance of the carriage.

Specific features of the present form of my invention will be described in detail in connection with the accompanying drawings,

Wherein Figure 1 is a fragmentary vertical front to rear sectional view of the upper part of a Monarch typewriting machine embodying my invention. Fig. 2 is a fragmentary plan View of the upper part of said machine. Fig. 3 is a fragmentary front elevation partly in section showing details of the carriage releasing mechanism and ribbon cutout devices. Fig, 4 is a vertical sectional view of the delivery spool or carrier and-the mounting of the same. Fig. 5 is a horizontal= sectional view of the devices which directly engage with the ribbon and feed the same lengthwise.

In the various views parts areomitted and broken away and only so much of the machine is shown as isnecessa-ry to a clear un derstanding of the invention.

'j Referring especially to Fig. 1, the main grooved track rails 4.

frame of the machine comprises posts 1 supporting a top plate 2 from which rise standards 23 to which are secured longitudinally Said track rails cooperate with antifriction balls 5, which balls also engage top and bottom grooves in a slide bar 6, said slide bar being comprised in a platen frame or carrier which further includes end bars 7 extending forward from the ends of the slide bar and supporting an axle S of a rotary platen 9. Key controlled printing instrumentalities (not shown) cooperate with the front-face of said platen which is provided with the usual or suitable line-spacing devices. The platen and-platen carrier or carriage are power driven, being constantly urged leftward by a carriage power or spring drum 10 which is connected with the carriage by a band or strap 11. Arms 12, pivoted each at 12 on the end bars 7 support a feed rack 12-) which is normally maintained by spring means 14 in mesh with a feed pinion 15 which is operatively connected with a toothed cscapement. wheel 16. Cooperating with the escapement wheel are other escapement devices or dogs (not shown) which are controlled by the printing keys, so that at each actuation of a printing key the escapement devices co-act to permit a letter space advance movement of the carriage under the pull of the spring drum 10. The carriage may be released from the escapcment; devices by a depression of one or another of the release keys 1?, one of which is arrai'iged at each end of the carriage and is rigidly connected to the contiguous pivot portion 12of the associate arm 12, the construction being such that the depression of either release key operates to lift the feed rack 13 from the pinion 15. The carriage is also adapted to be released by the operation of a tabulator key 18. Said key, as heretofore, is secured at the front end of a push rod 19 which bears in the right-hand front corner post and is pivotally connected at its rear end with the upright arm of a bell crank 20. the other arm of said bell crank being connected by a link 21 with the right-hand arm of a lever 22 fulcrumed at 23 in a bracket 24 Said lever 22 is pivotally connected at 25 with a lifter 26 having shoes 27 underlying the feed rack 13 and adapted to lift the same from enga e ment with the pinion 1.5 when the tabulator key 18 is pushed in. Secured as by rivets 28 to the lifter 26 and extending upward behind the feed rackis an extension 25) which is adapted to engage with a tabulator stop 30 pivoted at 31 to a fixed bracket 32 and provided with a spring which normally maintains said stop in the position shown in Fig. 1. The operation of the tabulator key 18 lifts the extension 21 and causes it to swing the frame stop 30 down into the path of column stops 34 mounted on a stop bar 35 carried by the carriage. As the operation of the tabulator key 18 also releases the carriage as heretofore explained, said carriage will move continuously leftward until arrested by the engagement of one of the column stops 34 with the frame stop 30. The operation of the tabulator mechanism need not be fur ther explained herein.

Referring now to the novel parts of my present invention, I preferably employ for printing purposes a narrow paper strip or ribbon 36 which replaces the usual inked fabric or ribbon. The strip or ribbon 36 is of thin material and preferably is covered with carbon or other inking material on one surface only, namely, the inner surface or that one which faces the printing face of the platen; The inking strip or carboned-paper strip or ribbon is preferably narrower than the ordinary ribbon which it replaces, the strip 36 shown in the present case being 5/16 in width. strip 36 is wound on a core piece or annulus 37 of pasteboard or the like and forms a supply the left-hand spool cup or container 38, heretofore provided on the top plate of the machine (Fig. 4). To support the supply roll I provide a holder comprising a disk 39 which fits within the spool cup and is supported in turn on the hub portion 40 of a shaft 41 which turns in a fixed bearing 42 integral with the top plate. A collar 43 pinned at 44 to the lower end of the shaft 41 below the bearing 42 prevents accidental displacement of the shaft 41. The upper portion 41 of the shaft 41. is enlarged and projects above the hub portion 40. The disk 39 is fotced down over the shaft portion 41 into contact with the top of the collar 40 and is suitably secured in place. Projecting upward from the disk 35) are a plurality of pointed pins 45, four in the present instance, arranged so that the core 37 will fit loosely over them. The pins 45 thus provide a four-point bearing for the supply roll of carbon paper and enable it to turn freely thereon and independently of the disk 39. The supply roll holder also comprises a companion disk or flange 46, which fits down over the shaft portion 41 and provides a cover for the supply roll. Said disk 46 is provided with a sleeve or hub portion 47 which fits over the shaft and contacts at its bottom with the disk 39 and is of such length as to hold the disk 46 out of contact with the supply roll 36.

The loose or free end of the carbon strip is let off from the supply roll passing through a cutaway or slot 48 formed in the left-hand spool cup at the inner side thereof. Centrally of the machine the paper strip is threaded through a vibratory ribbon The inking 1 roll which is adapted to fit into lever 50, said devices being actuated from the printing keys so that at printing operation the operating lever is turned on its fulcrum and lifts the vibrator 49 from normal position below the printing point as shown in Fig. 1 until the paper strip 36 is presented opposite the printin point. its vibratory movements the ri bon carrier or vibrator is guided by an upright guide 51 secured to the top plate.

The paper ribbon 36 is drawn off the supply roll at the left-hand side and fed stepby-step through the vibrator by devices at the right-hand side of the machine and some of which are within the right-hand spool cup 38, said spool cup being cut away at its rear side as indicated at 52 to permit the strip feeding devices to coiiperate properly. Said strip feeding devices comprise a rotary driving member or wheel 53 of large diameter which is arranged in the right-hand spool 1 cup 38, as appears from Figs.- 1 and 2. The

wheel 53 comprises a core 54 of wood orthe like which is covered by a sheath 55 preferably of rubber. The wheel 53 is provided with a bottom flange 56 and a top flange ,57 and is driven on-or otherwise secured to the upper end portion .58 of a vertically arranged shaft 59 which turns in a bearing 60 fixed to the top plate and depending therefrom. The driving wheel as a whole is.

seated on an enlargement or hub 61 on the shaft 59, said .hub engaging a boss 2 on the top plate. r

The driving member or wheel 53 is connected with the spring drum 10 so as to re ceive motion therefrom by connections which comprise a bevel gear wheel 62 secured to the lower end of the shaft 59 and engaging at its upper face with a small beveled pinion 63 fixed to the forward end of a horizontal shaft 64, said shaft turning in lugs 65 depending from the top plate. Fixed tothe rear end of the shaft 64 is a beveled gear' wheel 66 which is constantly in mesh with a beveled pinion 67 (Figs. 1 and 2) secured tothe right-hand end of a power or driving shaft 68, said shaft extending horizontally beneath the top plate and turningin bearings 69 depending therefrom. Fixed to the left-hand end of the driving shaft 68 a small beveled gear 70 which constantly meshes with a corresponding gear 71, said gear 'beingconnectible by a pawl 72 and ratchet wheel 73 with the spring drum 10 so as to receive motion from said spring drum when it is turning to advance the carriage in printing direction. It will be observed that the connections between the spring drum and the wheel or driving member 53 correspond substantially with the connections. heretofore employed between t the spring drum and the ribbon spools. However, in the present lnstance thedrivrng shaft 68 is not movable endwise but is ma1nstained so that the pinion 67 and the gear wheel 66 are always in mesh.

Co-acting with the sheath or periphery 55 of the driving wheel is a small wheel or roller 74 having an outer surface of rubber or the like said roller being arranged midway in the opening or slot, 52 and being pivoted on an upright stud or screw pin 75 of a hand lever 77 which is fulcrumed at 78 Ma stud rising from the top plate, the hand lever extending forward below the driving wheel and having an arm 79 which extends through a slot 38 in the righthand spool cup, said arm,79 terminating in an upright key or fingerpiece 80 in front of said spool secured to the rearwardly extending arm 76 3 cup. Said hand lever 77 further comprises an-arm 81 extending rightward from the arm 76 and bent downward at right angles providing a vertical arm or extension 82' which extends through a slot- 83 in the top plate 2. A coiled spring 84 connects the arm 81 of the lever 77 with an arm or anchor 85 secured by a screw 86 to the top plate, said spring, as will be apparent from Fig. 2, tending constantly to maintain the roller 74 in frictionalengagement with the periphery of the driving wheel 53. On' loosening the screw 86 the arm 85 may be adjusted to vary the tension of the spring 84. By pressing the special key or finger piece 80 toward the right the spring 84 may be overcome and the roller 74 moved rearward out of engagement with the wheel 53, thus enabling the paper strip 36 to be arranged between said roller and said wheel so that said strip'will be frictionally' engaged by these co-acting rotary devices when the finger piece 80 is released, permitting the spring 84 to restore the roller 7 4. As appears from Fig. 1 the height of the roller 74 is less than the distance bet-ween the flanges 56 and 57 of the driving wheel said tlangesinto engagement with the surface ofthe driving wheel or with the paper strip. The height of the guiding wheel or its width between the flanges 56 and 57 is such that the narrow carbon strip 36 may readily be accommodated and'the diameter of the driving wheel is such that the turning of the spring drum step-by ste1a to advance the carriage letter space distances will cause the driving wheel to turn step-by-step to fore and aft of the machine.

such anextent that the carbon strip 36 will be advanced at a uniform rate by reason of the frictional feed between the driving wheel 53 and the roller 74, which rate is of sufficient extent to cause th upright portions of successive type impressions to clear each other. The result is that the carbon strip will be used uniformly throughout its entire length. Since one set of type impressions practically exhausts the carbon carried by the rear or inner surface of the printing portion of'the strip, the used portion of the carbon strip may be torn off and thrown away after'it passes to the right and from between the feed devices 74 and 53.

Guiding devices are provided to insure that the paper strip 36 shall always cooperate properly with the feed rollers 53 and 7 1. Said devices comprise a hook-like guide 87 (Figs. 1 and 2) secured to the rim of the right-hand spool cup 38 at the left of the opening 52. The closed end of the hook or guide 87 is uppermost so that the paper strip or ribbon will be prevented from rising even if it should escape from under the flange 57. A similar hooklike guide 88 may be arranged at the right of the opening 52 and mounted on the rim at the right-hand spool cup 38. The closed portion of the hook or guide 88 at the bottom instead of at the top so that the paper tape or ribbon will be prevented from dropping down out of the control of its feeding devices.

In order to insure that the feeding devices shall be rendered inoperative when the tabulating mechanism is actuated to cause a continuous run of the carriage, connections are provided between the tabulating mechanism and the roller 74, such that when the tabulating key 18 is pressed in, the roller 74 will be moved out of operative engagement with the wheel or roller 53. Said con nections comprise a swinging arm 90'which is pivoted at 91 to a bracket 92 fixed to and depending from the top plate 2, the arm 90 being so mounted that it will swing freely A finger or lug 93 is secured to the push rod 19 by a set screw 94, said finger projecting horizontally leftward from the push rod 19 in front of the swinging arm 90 and in position to coact with the lower portion of said arm when the tabulator key 18 is pushed in, the construction being such that the finger 93 then acts to swing the arm 90 rearward on its pivot 91. The arm 90 is provided with a lateral extension 90 and this rearward movement of said arm causes the extension 90 to act against the lower end of the down ward extension 82. The result is that as the arm 90 swings rearward it acts through the extension or offset 90' to turn the lever 77 on its pivot 78 and move the roller 74 out of cooperative engagement with the paper strip or ribbon. In other words, the actuation of the tabulating mechanism operates automatically to separate the feeding devices for the paper strip or ribbon 36 and renders said feeding devices inoperative.

Means are also provided for separating or rendering inoperative the paper strip feeding devices when one of the release keys 17 is actuated, said means comprising connections between the feed rack 13 and the extension 82 of the lever 77. Said connections include a lip 95 suitably secured to the feed rack 13 and projecting horizontally rearward therefrom. said lip extending longitudinally of said feed rack and under the horizontally bent upper port-ion 96 of a vertical extension 97 formed at the end of the left-hand arm of a lever 98 having a fixed fulcrum 99. The means as thus far described and comprising the lip 95 and lever 98 are included in the rack lock mechanism of the Monarch machine and need not be further set forth herein. It will be understood that during the to and fro movements of the carriage the lip 95 runs along beneath the horizontal portion 96 of the lever 98 so that if at any time thecarriage is released by depressing one of the keys 17 and raising the feed rack 13, the lip 95 will act on the part 90 to turn the lever 98, lifting that portion of the lever to the left of the fulcrum 99 and lowering the portion or arm at the right of said fulcrum.

In carrying out my invention I provide an extension from the right-hand arm of the lever 98, said extension being formed preferably integral with said lever arm although it need not be. Said extension comprises a downwardly bent portion98 and an angular horizontal portion composed of a forward extension or offset 98 and a rightward extension 98 from the forward end of said offset. The end or portion 98 is seated in a notch 100 in the forward end of the horizontal arm 101 of a bell crank 102. Said bell crank is fulcrumed at 103 to a bracket or lug 104 fixed to and depend ing from the top plate 2. The bell crank 102 further comprises a depending arm 105 which is pivotally connected at 106 with a forwardly extending horizontal link 107, the forward end of said link being connected at 108 with the extension 82. It will be understood that when one of the keys 17 is actuated to release the carriage by lifting the feed rack 13 the right-hand arm of the lever 98 will be depressed and the extension 98 will act on the lever arm 101 to swing it downward about the pivot 103, the other arm 105 of the bell crank 102 being swung rearward a corresponding extent. This rearward movement of the arm 105 pulls the link 107 rearward, said link acting through the arm 82 to swing the lever 77 on its pivot and throw the feed roller 74: out of action.

In other words, the release of 60 tive.

ply device during the step-by-step movements of the carriage, and connections between said means and the carriage driving mechanism, said means feeding the paper ribbon out of the machine, the arrangement permitting the paper ribbon readily to be torn away after passing said means. I
